I’ve been running another test for StumbleUpon Ads to try and work out the value of the visitors it brings in.

For this test I was simply interested in seing how long each visitor spent on the blog to try and judge the “visitor value”, again I was sending the visitors to my “internet marketing” and “Blogging” related blogs.

The sample was over 2,000 visitors and on average each visitor only spent 29.4 seconds on the site before leaving, and less than on in each 10 visitors would leave the site via an “affiliate link” of some sort.

Compare this with recent visitors I’ve been getting from two other Web 2 social bookmarking sites and you can see there’s quite a difference:

Sphinn - each visitor spends on average 1 min and 36 seconds on the site and almost 6% click on a “montezied” link to leave.

You may not even have realised that Stumbleupon.com offer an advertising option,

I didn’t until last week, when I found out thanks to Yaro Stark.

obviously I needed to go and have a play to see whether it’s an undiscovered gem of traffic, or not…

You can listen to my thoughts about the results I received on the short podcast below, it’s less than 4 minutes long, so you shouldn’t fall asleep..

But I’ll give a quick written summary of my results as well.

first it’s worth noting that you’re not paying for “ad displays” or even clicks on ads, you’re paying for actual visitors to your site, as your site is added to the selection of sites in your chosen category that are presented to Stumbleupon users to “stumble” and vote on
